Line Chart from Public Google Spreadsheet

[Glenn Tremblett]

Hi Folks,

I am new to Google Charts, and wondering if someone can help me get started with creating a chart using data from a public Google Spreadsheet. I have no problem creating a line chart using manually entered values (as described here: https://developers.google.com/chart/interactive/docs/gallery/linechart), but for some reason no data is showing when I try to use the data from my public spreadsheet. I am attempting to follow the instructions here: https://developers.google.com/chart/interactive/docs/spreadsheets

Can anyone point me in the direction of where I may be going wrong?

My spreadsheet can be found here: https://docs.google.com/spreadsheets/d/1c4axGPSXmJBGwbcwWmSSir_uYAa92lao1eg98hUjzv4/edit#gid=0

Thanks!

Forgot to mention, 

This is what I'm currently trying (unsuccessfully): 

    function drawSheetName() {
      var queryString = encodeURIComponent('SELECT A, H, O, Q, R, U LIMIT 5 OFFSET 8');


      var query = new google.visualization.Query(
          'https://docs.google.com/spreadsheets/d/1c4axGPSXmJBGwbcwWmSSir_uYAa92lao1eg98hUjzv4=Sheet1&headers=1' + queryString);
      query.send(handleSampleDataQueryResponse);
    }


    function handleSampleDataQueryResponse(response) {
      if (response.isError()) {
        alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
        return;
      }


      var data = response.getDataTable();
      var chart = new google.visualization.LineChart(document.getElementById('line_chart'));
      chart.draw(data, { height: 400 });
    }
